European Coatings Journal - 15.05.2020 | RADIAT ION CURING PRODUCT OVERVIEW


As a rule, coatings dry, or better cure, by energy input - just like almost any other chemical reaction. For some, the ambient temperature is sufficient as long as it does not fall below a certain value. Others require temperatures above 200 °C, such as coil coatings, for example. Another type of activation is based on irradiation with high energy light. The photoinitiators contained in the coating decompose to radicals and start a classical radical polymerisation. This is quite energy-intensive - so the idea of using LED technology is logical. In a ...
